or by thermostatic control.

A still further object of the invention is that when the proper mixture of oil and air has been obtained, both may be increased or decreased simultaneously by one system of actuating levers.

Referring to the drawings, Fig. is an ele- .vation of the fan, rheostat, and pipe valve.

Fig. 2 is a top view of the mechanism. 1 1s a pan housing mounted on a base 2,

and substantially fastened thereto by means being connected with the shaft of the fan,

. it Wlll in; the dotted lines A, in the direction of the l of brackets 3, said brackets being firmly at tached to the flange of the fan, and the base, by means of the screws 4. 5 is the stand supporting an electric motor 6, said motor which is operatively inclosed in said housing.

is a pipe connected to the outlet of said fan, and also to an oil burner, said burner not being shown in the drawings, and the said burner may be any one of the forced air type. 8 is a rheostat, mounted on legs 9, said legs functioning as supporting means for an oil pipe 10 and the said pipe being firmly fastened thereto by means of yokes 11. 12 is a valve positioned in said pipe said valve having a shank 13 adapted to centrally engage with a bar 14, said bar having holes 15, drilled in close proximity to each other, in each end of said bar. 16 is a shutter, adapted to close the air inlet M which is the air'supply openin for the ian, the said utter 16 is pivota an arm 18, said arm aving holes drilled for the purpose hereinafter described. 19 is the rheostat contact arm pivoted at 20 and adapted to on rheostat points-21 for e purpose 0 controlling t e eed of the motor. 22 is a. lever attached t d a thermostatically controlled mechanism (not shown) the said thermostat being set for a certain temperature so that when the contact is made cause the said lever to rotate, follow- {lmounted at 17 and has arrow, which movement partly'closes the valve 12, reducing the oil supply, and at the same time changing the rheostat which lowers the speed of the motor 6 and closing the shutter 16, the operation of which reduces the flow of the oil and the pressureof the air, as heretofore described. 23 is a connecting rod between the thermostat arm and the oilvalve arm 14.

24: is a connecting rod from the valve arm 14 to the rheostat arm 19, and 25 is a connecting rod from the said valve arm to the shutter arm, and the connections are so made so that any movement of the thermostat will afiect the motor, valve and shutter simultaneously.

It will be understood that when the shutter is being closed, the flow of air being cut off, a resistance is set up in the revolutions of the fan, whichassists the motor in reducing its speed, therefore quicker action is had than by reducin the motor speed or closing the shutter in ependently of each other. I

When all of the adjustable elements are in the positions represented by Fig. 1, of the drawing, the air-intake, M, of the blower is fully exposed; the fuel justed for giving the maximum flow of oil to the burner; and the rheostat arm, 19, is

oil valve, 12, is ad-' at one end of its throw, giving the motor, 6,

tegral therewith to function at the intake of the fan, and legs supporting the said rheostat, said legs being rigidly connected to the ho of the fan, a fuel oil pi e having a valve t erein, said pipe carried by the legs, a bar centrally connected to the valve, 21' lurality of apertures lon itudinally spaced in both ends of the bar, a t ermostat controlling ever having a plurality of apertures longitudinally spaced therein, a rheostat contact connecting the last said end of the valve bar arm pivotally rocking from one end to reguto the free end of the rheostat contact arm, late the current, a connecting rod from one all for simultaneously governing the flow of 1 end of the valve bar to the thermostat lever, the fuel oil and air blast by thermostatic 5 a rod connecting the opposite end of said bar actuating means.

to the arm of the fan intake valve, a rod intermediately positioned to the first said rods JOSEPH SCHERMULY.
